Schedule 13Gregulatory
"Item 1(a) and header identifying the form type"
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

Which State Street entities are named in the filing?
The filing lists multiple State Street adviser entities under Item 7, including SSGA Funds Management, Inc., State Street Global Advisors Europe Limited, and others. These entities are identified as parties through which the position is held.
Is this Schedule 13G indicative of active control of Oceaneering?
